Abstract: 1,236,210. Nuclear power plant. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 4 Feb., 1969 [12 Feb., 1968; 5 March, 1968; 18 March, 1968], Nos. 6896/68, 10750/68 and 13099/68. Heading G6C. In a steam generating nuclear reactor, having a positive void coefficient of reactivity, an immediate coolant supply is introduced upon an interruption of the normal coolant flow. Voiding within the fuel channels is delayed for a period long enough for the emergency shut down and cooling systems to be operated. In the reactor fuel tubes, 1 (Fig. 1), during normal operation, coolant light water is circulated along the fuel tubes 2 by the pump 9, the steam generated being directed to the turbine 5. In the event of a breach of a primary circuit at 9, a flow of coolant from the hydraulic accumulator 13 is urged into the tubes 1 by pressurized helium gas isolated from the water by the flexible membrane 27. The non-return valves 15 prevent water being discharged through the breach. The non-return valves 16 prevent rapid depressurization of the coolant circuit as a result of a breach at 13. The Venturi constriction 12 also limits outflow from tubes 2 but offers a small impedance to normal flow. In a modification, the accumulator is pressurized with steam generated by an electric immersion heater.

Abstract: 780,650. Pneumatic conveyers. UNITED STATES RUBBER CO. April 30, 1956 [July 11, 1955], No. 13180/56. Class 78(1). A finely comminuted solid is conveyed through a collapsible hose by pumping it into one end of the hose after fluidization and at the same time applying suction to the other end by means of a pump operated at a volumetric rate greater than that at which the solid is pumped into the hose. The solid falls from the container C through a sleeve valve S into a pipe 10 and on to a piece of porous fabric 13 which directs it to a pump 15. Air or an inert gas, e.g. nitrogen, under a comparatively low pressure is supplied to the plenum chamber 14 below the fabric 13. The pump 15 forces the material into the hose 16 which is gas impervious and will collapse at least 50 per cent, but not more than 95 per cent, under a differential pressure of approximately atmospheric pressure. The suction applied by the pump 17 causes the powder to move through the hose in batches B with the hose more or less collapsed between them.

Title: A process for producing frozen meat especially fish
IPC: A23B4/06
Filed: 1955-05-09
Abstract: 781,620. Frozen fish blocks. NORSK FROSSENFISK A/L. May 9, 1955 [May 7, 1954], No. 13316/55. Class 49. Frozen meat, particularly frozen fish, is prepared in flat blocks of uniform shape and weight by packing a former with pieces of the meat in fresh condition superposed with the meat fibres horizontal and the meat fibres of the different pieces generally parallel, deforming the packed pieces by a pressure of at least 0.5 kg./sq. cm. above atmospheric applied vertically to cause the pieces to fill completely the cross-section of the former, freezing the block of pieces so formed, and then cutting the frozen block along planes at right angles to the direction in which it was pressed. Before the pressing, the meat pieces may be treated with a substance which assists their adherence to one another, e.g. the pieces may be dipped into a solution containing actomysin extracted from muscle tissue. According to procedure described with reference to Figs. 1 and 2, fish fillets 2 are pressed in a tall former 1, of rectangular cross-section, having a movable bottom 3 which fits closely in the former and is the head of a lower piston, and having a movable top 7 which is the head of an upper piston. A number of the fillets are superposed, with head ends and tail ends alternating. on the bottom 3 (position A), the top 7 is moved down to press the fillets (position B), the lower piston is released to allow the bottom 3 to fall sufficiently to provide in the former 1 a packing space the same as for the first packing (position C), the top 7 is removed and more fillets are introduced (position D), and again the top 7 is brought down to exert pressure, the operations being repeated, with a lowering of the bottom 3 after each pressing, until a block of fillets ready for the freezing is produced (position E). Expulsion of the block from the former 1 after the freezing may be aided by operation of the top 7, and also, if desired, by momentarily heating the former 1. Saws may be employed for subdivision of the frozen block to conveniently packaged rectangular slabs.

Title: Improvements in or relating to travelling-wave tubes
IPC: H01J25/46
Filed: 1955-05-10
Abstract: 782,768. Travelling wave tubes. SIEMENS & HALSKE AKT.-GES. May 10, 1955 [May 11, 1954], No. 13510/55. Class 39(1). The slow wave structure of a travelling wave tube comprises a wire or strip wound in a plurality of helical turns having inductive portions 4, Fig. 2, and capacitive portions 5, 6, the capacitive portions only lying in the region of energy exchange with the electron beam 9 or beams and the inductive portions being longer than the capacitive portions. The loops 4 may be circular or elliptical. In manufacture, metal wire or strip is wound on a dumb-bell-shaped mandrel after which the mandrel is removed and the turns pulled out to obtain the structure of Fig. 2. Due, however, to the elasticity of the wire or strip used the inductive loops of successive turns are angularly displaced, as shown in Fig. 3, the angular displacement serving to capacitively decouple the inductive loops. The capacitive parts 5, 6 can be bent out slightly to ensure better interaction with the beam which is of circular cross-section, the mandrel having correspondingly outwardly projecting portions. The circumference per turn is approximately equal to the operating wavelength and adjacent parts 5, 6 are of opposite phase. There may be a plurality of electron beams. In further modifications, each helix turn may have four inductive loops and four capacitive portions, Fig. 6 (not shown) or an inductive loop the ends of which are connected by a very small capacitive loop through which the beam passes, Fig. 5 (not shown). In Fig. 5 the circumferential length of a complete turn is one half wavelength, while in Fig. 6 the circumference of a complete turn is twice the wavelength.

Abstract: 992,929. Heating or cooling garments. MINISTER OF AVIATION. March 26, 1964 [April 5, 1963], No. 13635/63. Heading A3V. Apparatus for controlling body temperature comprises a liquid pipe circuit of which some pipes run generally outwardly from the central region of the trunk portion of a garment and are so attached to the garment that at least part of the inner face of the garment which contacts the body is formed of exposed walls of these pipes. A garment which may be a pressure suit comprises an inlet manifold 11 in circuit with a pump 16 and cooler 17 and an outlet manifold 14 connected to a number of small bore, flexible tubes leading off from the ends of parts 11a, 11b of the manifold. The cooler comprises a water jacket 24 connected to the garment pipes at inlet 25 and outlet 26 and surrounding a cooling evaporator chamber 20 connected at one end to a source of vacuum and at the other end to a water resrvoir 22, through control valve 23. The low pressure draws water into the chamber where it expands and cools the walls of the chamber. Various forms of cooler are described. The jacket may surround a reservoir for water which evaporates and is obsorbed by a desiccant. The device can be reused by heating the desiccator to return the water to the reservoir. The reservoir 40 may be connected to a heat exchanger 44 with connections 48, 49 for the garment pipes and a tube 45 to a desiccating chamber 46 at a low pressure with desiccator 47. The heat exchanger may be in a chamber open to an atmospheric source of low pressure. A nozzle in the chamber outlet maintains the difference in pressure. The dessiccator may be in the form of a flat box with external fins. The coolant may be melting ice and a three way valve allows part of the garment cooling liquid to flow through the melting ice. Part of the garment liquid may flow to the evaporator chamber which has a desiccator and is at low pressure, the remainder of the liquid flows to the jacket surrounding the chamber. The garment may be heated by housing the heat exchanger in a duct and heating by an appliance such as a butane burning stove.
